Electromagnetic (EM) waves in the terahertz (THz) regime contribute to important applications in communications, security imaging, and bio- and chemical sensing. Such wide applicability has resulted in significant technological ...
In a new publication from Opto-Electronic Advances, researchers led by Professor Liu Yan from Xidian University, China and Professor Gan Xuetao from Northwestern Polytechnical University, China, consider generation and application ...
A team of scientists at Los Alamos National Laboratory propose that modulated quantum metasurfaces can control all properties of photonic qubits, a breakthrough that could impact the fields of quantum information, communications, ...
Cornell researchers have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation, paving the way for new scientific tools for high-resolution imaging and studying physical ...
When we think about singularities, we tend to think of massive black holes in faraway galaxies or a distant future with runaway AI, but singularities are all around us. Singularities are simply a place where certain parameters ...
Screens may be larger on smartphones now, but nearly every other component is designed to be thinner, flatter and tinier than ever before. The engineering requires a shift from shapely, and bulky lenses to the development ...
A research team, led by Professor Dai-Sik Kim in the Department of Â鶹ÒùÔºics at UNIST has developed a new technique of predefining the crack pattern on a flexible substrate by a sequential deposition of metallic layers which ...
Optical metasurfaces can unprecedently regulate versatile wavefronts at the subwavelength scale. Most well-established optical metasurfaces are, however, static and feature well-defined optical responses that are determined ...
Scientists have developed a high-efficiency beam steering angle expander consisting of two liquid crystal polymeric diffractive optical elements. For a LiDAR (light detection and ranging) operating at 905 nm, the steering ...
The ability to precisely control the various properties of laser light is critical to much of the technology that we use today, from commercial virtual reality (VR) headsets to microscopic imaging for biomedical research. ...
